My Chem 101 prof said it's often used to denature the lab ethanol -- doesn't affect most of its uses as a reagent, and makes it really easy to tell who's stealing some for free booze without causing permanent damage.

Take the case of di-tert-butyl peroxide. Let's do what Derek Lowe did not initially, and imagine that someone somehow managed to cram another O in between the 2 Os holding the center of the molecule together. Now we've got some decomposition products that look like they're ready to party (a few CH3s bound to a C that's feeling cranky) and some fresh oxidizer that's ready to mingle (that single O from the middle of the chain), and the real fun can begin

I realize this is a more apt question for a general chemistry thread, but this is the one I lurk so here goes: Why is it that a mol of ideal gas' volume at STP is 22.4 liters? It seems with the "1 Atmosphere of pressure" term there could have been room to fudge it a bit to end up at a rounder volume. Was 1 atm already agreed on by convention as 101.3 kPa?

The standard atmosphere came first, as the agreed-upon height of a column of mercury. The Pascal came later as a Newton per square meter and 101.3 of them equalled an atmosphere.

I'm fairly certain that the standard atmospheric pressure was arrived upon by averaging years of measurements anyway. It's not necessarily representative of anything on any specific day, but it's not really arbitrary either.

Pressure was a tool to measure something like an ideal gas in thought experiments. Not the other way around to define it. Physics has a way of laughing at people looking for even numbers.

I was reading the fart stories thread in GBS, and it got me wondering. What better place to ask, than a bunch of chemistry-inclined goons? Why do farts in the shower smell more awful and more moist, for lack of a better word, than farts outside in the dry? I'm sure being in a small enclosed space has something to do with it, but at least for me it definitely also changes the character of the fart, vs. let's say a dutch oven. Are there actually chemicals in a toot that would smell different if they got hydrated (not sure if I'm using the word right there)? It's pretty goddamn dry where I live, would a ripper on a 100% humidity day smell more similar to a shower fart?

I would bet it's more macro scale than chemistry. You've got a ton of air currents & aerosol droplets in the shower.

Sulfurous molecules are literally the stuff of egg farts. They are mildly acidic which creates a one two punch to the nose: the water droplets end up being acidified slightly increasing the kick, and the sulfurous part is potentiated by that missing hydrogen to really buzz the hell out of your nose. Add in that a shower is a kinetic whirlwind from your butt to your nose and shower farts hit fast and hard.
